In this thesis the design of sanitary sewer
systea and septic tank for Kushville, we were
materially assisted by the fact that the work
was at that time under actual design by Pro-
fesser Phillips, from whom much valuable in-
fornatiou, as well as most of the fundamental
data, was obtained,. A thorough understanding
of the conditions existing in to Rushville
has rendered the v/ork far more satisfactory
as well as interesting, and the writers take
this opportunity of expressing their appre-
ciation to Professor Phillips for his
assistance and interest in the work*

Rushville is a small tov/n of perhaps
four thousand inhabitants, in the central
portion of Schayler County, on the Chicago,
Burlington! and Quincy Railroad. The popu-
lation is made up of well to do farmers,
and has been increasing slowly during the
last ten years. When the idea of in^
stalling a sewer system was first taken up,
it was found, after careful consideration
of the resoiirces of the tovm, that it would
not be advisable to attempt to finance a

v.'ork which would include both sanitary and
st'orn sewers, as a water supply system was
to be included in the work, Ttien also the
topography of the ground is such that
natural water cources are available for the
drainage of the surface water.. The merits
of various systems of pui'if ications were
weighed and in the end the septic tank
treatment v/as adopted. The degree of puri-
fication accomplished by this method was
found to be sufficient and an available
creek was at hand into which the effluent
of the tank could be discharged,.

Tl-ie procedure adopted in the work was
as follows:

1, Field work..

2, Platts of profiles and Topograp-
hical map,

3, Layout and design of pipe lines.

of pipe lines and manholes could be shown..

graphic map of the tovm was begun, A map
showing the lot subdivision of the town was
obtained and on this contour shov/ing two
foot differences in elevation v;ere
sketched,. A tracing was then made, from
which prints were obtained on which to
layout the pipe lines,.

(3) It was found t?iat the general
slope of the ground was from the north-
west to the southeast section of town and
so the sewers were designed to begin out
on Macomb Road and run generally in a
south and easterly direction. The main
lines were designed to run south on Jackson,
Ivlonroe and Morgan streets and east- on Clinton,
combining finally at the corner of Clinton
and Llorgan, the smaller lines all connecting
into these. In most cases an eight inch sewer.
has been used. Much of this could be of
smaller size but eight inches is regarded as
a practical minimum,.

to each lot, the Roosevelt Avenue sewer
would have a discharge of 236X100-^5,600
gallons per day, or 2.36 cubic feet per

With this velocity a discharge of 3.42
cubic feet per second will be obtained.

The grades used on the snxaller branches
averaged from four to six feet in a thousand,
while the main lines were laid at a grade of
two feet in a thousand.

A flush tank is used at each dead end,
details of which are shown in accompanying
prints. It is advisable that these tanks
should discharge from 500 to 800 gallons at
least once in 24 hours intermittently
throughout the system.

Man}:ioles are placed at each street
intersections and at intervals, so that the
distance between manh oles does not exceed
350 feet. In some instances lamp holes have
been used to further aid in the care and main^
tenance of sewers.

EXCAVATION,

9, All excavations shall be by open cut from
the surface. No tunneling will be allowed, except
written permissioni be previously obtained from the
Engineer,

10. The contractor will be required to keep
the sides of the excavation vertical, by bracing or
otherv/ise; but no allowance will be nade therefor
unless the sane is left in the trench by written
order of the Engineer,.

11. The excavation, at the bottom, is to te
made and shaped as nearly as possible to fit the
lower halfi of the pipe to be laid, with holes cut
at the joints for the sockets to rest in, so
that the pipe shall have a uniform bearing on the
groand from end to end.

12, At tne heignt of half of the diameter of
the pipe from the bottom, tiiat is, at the height of
the greatest horizontal diameter of the pipe, all
trenches are to be eighteen inches wider than- the
greatest diameter of the pipe to be laid therein.

13. Tiie trench shall he dug to within six
inches of grade by measurement from the witness
stakes on the surface. The last six inches shalli
be taken out after the grade pegs have been set in
the bottom, of the ttench by the contractor under

leave at least one foot in the clear between their
outer surface and the eabanknent or timber v/hich
Tiay be used to protect it,.

15, "Erie approxiciate depth of the cutting
will be given by the Engineer before the excava-
tion is beguni. Grade and line will be given by
the Engineer every 25 feet at the bottom of the
trench, on stakes to be furnished and set by
the contractor; or on overhead pieces, from
which the position of the invert nay be determined

HAND MIXING,

9, If the concrete is mixed by hand, the
cement and aggregate shall be mixed and the
v/ater added on a tight platforia large enough
to provide space for the partially
simultaneous mixing of two batches of not
more than one cubic yard each. The sand
and cement shall be spread in their layers
and mixed dry until of uniform color. This
mixture may be spread upon the layer of
stone or the stone shovelled upon it before
adding the water, or it may be made into
a mortar before spreading it with the stone..
In the former method the materials shall be
turned at least three times,- in addition
to the mixing of the sand and cement already
mentioned, and in addition to the shovelling
from the platform to place or into the
vehicle for transportation,. In the latter
method, that is, if the sand and cement are
first made into mortar, the mass of mortar
and stone shall be turned at least twice,.
Whatever method is employed, the number
of turnings sliall be sufficient to produce
a resulting loose concrete of uniform color
and appearance, with the cement uniform;ly
distributed through the mass, the stones,,
thoroug?ily incorporated into the mortar and
the consistency unifom throughout, thus
producing a concrete uniform in color, and
homogeneous.

ACHINE MIXING.

10, If the concrete is inixed in a machine
mixer, a machine shall be selected into which
the materials, including the water, can be
precisely and regularly, proportioned, and
which will produce a concrete of uniform, con-
sistency and color with the stones and water
thoroughly nixed and incorporated with the
mortar, .

CONSISTENCY,

11, The mixture shall be wet ofi-
mushy, so soft that it will flow when) agitated,
but not so wet as to produce a separation of the
materials in transferring to the work,.

PLACING CONCRETE.

12, concrete shall be conveyed to place
in such a manner that there shall be no dis-
tinct, separation of the different ingredients,
or in cases where such separation inadvertently
occurs, the concrete shall be remixed before

placing. It shall bo placed in tlie work
inmiediately after mixing and deposited and
removed or agitated liy suitable tools in
such a manner, as to produce thoroughly
compact concrete of maximuiai density. No
concrete shall be ple.ced until the re-
inforcing has been placed and firmly secured
by wiring or other method to prevent dis-
placenent.. Concrete shall b.B frequently
wet for several days to prevent too rapid
drying out,. Concrete shall not be placed in
water, unless UTiavoidable. , ?/here concrete
must be placed under water, unusual care
must be taken to prevent the cement from:
being floated away,. This usually can be
accomplished in still water by placing
the concrete through a large pipe or tube, or
by means of a bottom dump concrete bucket..

Before placing fresh concrete, all
shavings and debris of every nature must be
removed and the old old concrete surface
thoroughly cleaned from all dirt tind scum
or laitance and drenched v;ith v/ater.
Noticeable vaids or stone pockets dis-
covered v/hen the forms are removed, , shall
be filled immediately with mortar mixed
in the same proportions as the mortar in the
concrete,. The lines and grades of the
completed concrete shall accurately conform
to the place annexed to and forming a part
of the specifications,.

PLACING REINFORCEMENT.

13, The reinforcenent shall accurately
conforn In the finished structure to the plans
annexed to and forming a part of these
specifications,.. All reinforcement shall be
free from rust, scale, or coating of an;;-
character, which would tend to reduce or de-
stroy the bond.. Before placing concrete the
reinforcement must be placed in the position^
required in the finished structure and each,
piece or member so firmly fixed as to positively
prevent any subsequent displacement,.

FREEZING Vf E A T H E R,

fraught v/ith danger unxier incompetent
direction.. Forms shall be thoroughly cleaned
before being used again,.

ORDINARY SURFACES,

16 (a) Surfaces shall have no special
treatment further than care in placing the
concrete to avoid noticeable voids or stone
pockets,. Forms shall be wet (except in
